Irving Oil delivered its first truckload of compressed natural gas, or CNG, to the McCain Foods plant in Easton, Maine, on May 10. Truck-delivered CNG is at the leading-edge of natural gas technology, said Paul Browning, Irving Oils president and CEO.

EASTON, Maine — Another company is beginning to offer compressed natural gas to commercial and industrial customers in northern Maine.

Irving Oil last Friday delivered its first truckload of compressed natural gas, or CNG, to McCain Foods’ processing facility in Easton.

Delivering compressed natural gas by truck is “at the leading-edge of natural gas technology,” Paul Browning, Irving Oil’s president and CEO, said in a statement.

Irving Oil, which has sold other forms of natural gas for roughly 13 years, began working on a plan to provide CNG by truck roughly 18 months ago, Darren Gillis, general manager at Irving Energy, told the Bangor Daily News on Thursday.

The company in April 2012 completed construction of a compressor station in Lincoln, New Brunswick, which takes natural gas off the Maritimes & Northeast Pipeline, compresses it, then trucks it to customers. The gas is coming from the Sable Offshore Energy Project, which produces natural gas off the coast of Nova Scotia.

It’s a two-hour drive from Lincoln, New Brunswick, to Easton, Maine, which is at the far end of the geographic reach of the compressor station, Gillis said. Beyond that, the trucking costs start eating into any savings produced from switching from oil to natural gas, he said.

Irving Oil is not the only company delivering CNG by truck to Maine customers.
